I have a '67 Bronco that I swapped in a '02 5.3. I want to switch over to the LS1/LS6 intake manifold to save clearance and helps looks. Now I know that the LS6 gains about 20HP over the LS1 manifold but those gains are only realized above 5k. I've been told that you lose power when removing the truck intake unless you go with the LS6 manifold. I don't spend a whole lot of time above 5k as this is a DD/off-roading rig. I have a LS1 manifold sitting in my garage right now should I use it or go pay $300+ for an LS6 manifold? Or will I lose too much torque getting rid of the truck manifold for either of these to make it worth it? FYI I will be installing a LS6 cam soon as well.
